Abstract: The respective meaning of fairness,impartiality,justice and equality is semantically similar to each other.They are internally correlated to one another,which makes them alternative terms on particular occasion.However,from the perspective of theoretical research,they differentiate in different contexts and fields,and the objects they might be applied to and their meanings are some what different as well,or rather each has its own focus.Under many circumstances,their relationships are truly intertwined.
